My major complain with the M80 is not the treble energy, the bright sound do not bother me at all, I like bright forward sound, but bright in the sense of upper highs, not on the midhighs, the mids were too present for my taste on the M80s, giving it a sound a little honky, not sure if that is the right term, but that is what sounds to be...
Now if someone like to waste money and pay more to get the same sound and fool later yourself into beleiving that you have superior set of speakers, go ahead, I simply go for what my ears tell me...
See, now you are describing what most of us hear, although I am sure your M3s must sound different than the ones I have heard as they were not bright at all and the mid range/highs were depressed.
As to your second comment I quoted, like you said you are going with what your ears hear, just as the rest of us are, I don't believe anyone is fooling themselves.
